The Chevrolet Cruze (J400) from 2016-2019 is a popular compact sedan known for its efficiency and technology features. Like most modern vehicles, it relies on a network of fuses and relays to manage its electrical systems.
The fuse box in the Cruze is located in two primary areas: the engine compartment and the interior, usually near the dashboard. The engine compartment fuse box handles high-power systems such as the engine control module, headlights, and cooling fans. The interior fuse box manages lower-power systems like the infotainment system, interior lights, and power windows. Fuses protect these circuits by disconnecting them if there’s an overload or short circuit, preventing damage.
Relays act as switches for high-current components like the fuel pump, starter motor, and air conditioning system. They allow low-current circuits to safely control these high-power devices. Regularly inspecting and maintaining the fuses and relays is important to ensure the smooth operation of critical electrical components and prevent potential electrical issues in the Cruze.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
